REFLECTOR: Franklin PZL fuel pump

[Ken C. Baker]

Jeff,
 
I believe that PZL originally manufactured the mechanically driven pumps
after they issued the emergency AD on the old style diaphragm pumps that
were failing. The part number will either be PLL-7-6R (26.11.8300) for
right-handed Franklin 6A350-C1, and 6A-350C1R engines, or PLL-7-6L
(26.11.8310) for left-handed Franklin 6A350-C1L engine.
 
We have an aircraft in the Service Center right now equipped with a Franklin
that we have been asked to finish. Since taking on the project, the owner
decided to try to fuel inject the engine, and the PZL mechanical fuel pump
is incapable of producing the pressures necessary for this. We have no real
need for the PZL mechanical pump anymore. If you're interested, contact me
off the Reflector.
 
I originally got the fuel pump in my possession from Brian Michalk. I'm sure
that he probably has another that he'd be willing to part with.
 
While on the subject, I don't suppose anyone on the Reflector is running a
left-handed Franklin? The 6A-350C1L model?
 
Best Regards,

Don,
 
I'm not sure about repair - but if you need a new AD compliant Franklin fuel
pump for a carbureted application on a 6A-350-C1R, I've got one.
 
Best,

My Franklin just started leaking oil around the fuel pump.  Not sure yet
exactly where it's coming from.  Don, any update on what you have done? John

 Oil is coming out of the vent hole in my PZL rotatory  fuel pump. Am I the
first one o have this problem? Does anyone know whether it can be repaired?
Looking at the illustated parts list, it seems to me that the only thing
that might be a candidate for replacement is something called a needle
bearing. Can anyone help me with this. The pump has less than one hundred
hours on it. If it cannot be repaied, does anyone know if or where a new one
might be available?  Donald Royer
